[ラットの血液像および血液化学に対する100μTの超低周波電磁界ばく露の影響] med./bio.

Effects of 100 µT extremely low frequency electromagnetic fields exposure on hematograms and blood chemistry in rats.

掲載誌: J Radiat Res 2016; 57 (1): 16-24

この研究は、100μT、50Hzの超低周波電磁界(ELF EMF)のばく露(20時間/日、ばく露期間3ヵ月)が、ラット健康全般に及ぼす影響を調べた。ラット(n=128)は、ELF EMFばく露群と擬似ばく露群に2分され、3ヵ月間、体重(2週間ごと)、食餌および水の摂取量(1週間ごと)を測定した。また、血液像パラメータを実験開始前と終了後に、血液化学パラメータを4週間ごとに分析した。その結果、ELF EMFばく露群の身体状況全般に影響は見られなかった;血液像および血液化学パラメータにも影響は見られなかった、と報告している。

研究目的(著者による)

The effect of exposure of rats to a 50 Hz magnetic field on hematologic parameters and the function of liver and kidneys should be investigated.

詳細情報

Rats were divided into two groups (n=64 each): 1) exposure and 2) sham exposure.

ばく露装置の詳細 exposure device was a rack made of plastics (1 x 2 x 2 m (L x W x H) with five floors made of bronze wires to produce magnetic field; the top and bottom floors were made of 400 turns and the internal floors were made of 200 turns of wire; inside the device, a four-floor shelf was placed, which was also made with plastic in the center, and the height of every floor was the same as that of the device (?); two un-restrained rats per cage
Sham exposure A sham exposure was conducted.

研究の主なアウトカム(著者による)

No significant differences were found between the exposure group (group 1) and the sham exposure group (group 2).
The authors conclude that exposure of rats to a 50 Hz magnetic field has no effect on the investigated hematologic parameters or the function of liver and kidneys.
